Spectacular photos in this year's Eureka photo prize competition take us to the wide expanse of the Western Australian outback, the undersea world of a majestic manta ray, the minute detail of nanoparticles and beyond.

Venture into the micro world of human anatomy and animals with teeth reinforced with iron, scales that reflect light and velvet 'fingers' on their skin captured by scientists from the Australian Microscopy and Microanalysis Research Facility.

The beauty and brutality of the animal kingdom is brought to life in exquisite detail by the finalists in the 'animal behaviour' category of the 2012 ANZANG Nature Photo Competition at the South Australian Museum.

Take a trip around some outstanding natural areas in these beautiful photos from Bush Heritage, a national non-profit organisation that preserves Australia's unique bush by buying high conservation value land and caring for it.
